type-B-diet input of 0.5 picocuries/day (.37 pCi/d plutoniua-239,—-240 +
-13 pCi/d americium-241), I estimate the following 30-year doses:
whole-body, .020 rem;
red marrow, .029 rem;
liver, .065 rem;
bone-surface, .365 rem. The Livermore doses are about a factor
Inhalation. It is the transuranics that are of consequence.J The
original estimates of dust intake were very much too high (Shinn Bt al
1980) and they have been reduced to make them more realistic (Robison
1988). The daily intake for adults is estimated now at .0037 piapcuries
for plutonium-239,-240, and .0012 for americium-241.
Their contmibution
to the effective whole-body-dose would be about .023 rem in 30 yeaars, and
about 0.35 rem to the bone marrow, .075 rem to liver, and .42 rem to bone
surface.
The matter is discussed in Note 10.
Summary. Using the input method, the calculations of
mmnitted
dose are in practical agreement with those of DOE-1982.
It shou] be
noted that these are for adults. It should also be noted that th
estimates depend directly on the assumed diets. The following tdbulation
